Cellular and biochemical parameters of lung injury and inflammation. A. Differential cell counts in BAL at 24 hours post-exposure. There were significant increases in lavaged neutrophils when rats were instilled with 1 mg/kg iron oxide or 10% wt Ag on SiO2. B. Biochemical parameters of injury/inflammation. Instillation of suspension of iron oxide (DDLS 1. 76 μm) or 10% wt Ag on SiO2 (DDLS 0. 19 μm) significantly increased myeloperoxidase (MPO), lactate dehydrogenase (LDH) and albumin compared with control. No significant change was observed in BAL hemoglobin levels. In addition, 10% wt Ag on SiO2 induced higher albumin levels compared with iron oxide. (* P < 0.05, vs. control, * P < 0.05, # iron oxide vs. 10% wt Ag on SiO2).
